Although handcuffed and wearing leg irons, a Massachusetts criminal defendant reportedly swung his arms and knocked a court officer down on Monday afternoon as he was being led from Plymouth District Court into a holding cell, prompting a nine-car response from state, county and local police.

The unidentified defendant and another inmate, who had both been on trial in a third-floor courtroom, were then transported back to state prison. One court officer went to the hospital in an ambulance and others sustained minor injuries, according to Fox 25 and the Patriot-Ledger.

The incident occurred after the jury had already exited to begin deliberating. Both prisoners refused medical treatment.
